Model: ER707-M2

Firmware Version:

I should say up front that I am a dilletante when it comes to networking. I have played around with it, but I do not truly know what I am doing. I am currently using a Netgear RS700 as primary router. However, it has not native failover or load balancing. I am considering adding aTP-Link ER707-M2 or similat TP-Link dual wan router to create failover capability. However, I would prefer to keep the RS700 as it is current setup. Is this possible and, if so, can you give me some guidance as to how to set it up? All thoughts appreciated. BTW, the main pirpose behind this is to eliminate/reduce current ISP instability.

You can do it by putting TP-Link between your Netgear and ISPs:

 

Then in TP-Link settings you have to mark, which ports are supposed to be WAN porta (those that are connected to Internet - your ISPs), and configure those ports (usually it's Dynamic IP, but some ISP may have differen way of connection - like PPPoE):

 

Once you set up your WANs, you can configure Fail Over feature:

<I can't upload the screenshot at the moment -_->

Transmission => Load Balancing => Link Backup

 

You can also configure Online Detection - which DNS server to use for that.

 

If it's configured properly, when primary link (ISP #1) goes offline, then the TP-Link will switch whole traffic to ISP #2. And once ISP #1 is back online, it will switch back.

 

The Netgear router you just connect as standard LAN device. (LAN port on TP-Link, WAN on Netgear).

Just make sure that subnets of TP-Link and Netgear's are different.

Also this will create double NAT in your network. Some TP-Link routers allows you to disable NAT on them - so you could do that. Or you can forward needed ports from TP-Link to Netgear.

This is doable. Refer to Raru's reply, the diagram.

But you gotta know how it works in load balance or failover: Common Questions About the Load Balancing, Link Backup(Failover) & Online Detection

 

Should work straight for most load balance/failover cases.

Hi,

 

It is possible, but may I ask, what do you need your current router for if you want to use TP-Link as well? Is there any particular reason to stick to Netgear now?

 

Cheers.

Maybe the answer is I shouldn't. However, this is a router I have purchased (for $700) only about 6 months ago. I am reluctant to bin it on that account alone. The rest is laziness. Everything in already set up in the netgear (addresses etc.), and I'd rather not have to recreate it. I was hoping to add the ER707-M2 just for the failover capability.

Re:Dual Wan Router (TP-Link ER707-M2) with Netgear RS700 as Primary
Wednesday

  @RaRu Thank you very much for your excellent and detailed response. I wonder if you (or another) could give a newbie a bit more guidance. You state:

 

"Just make sure that subnets of TP-Link and Netgear's are different".

 

Could you give me a little guidance asto how I go about this or where I might find instructions to do so? Adding the ER707 into the setup appears to have made my NAS resources (which have static IP addresses) unaccessible from outside the network.

 

"Also this will create double NAT in your network. Some TP-Link routers allows you to disable NAT on them - so you could do that. Or you can forward needed ports from TP-Link to Netgear."

 

Unfortunately, the option to disable NAT seems to have been removed for the ER707 or moved to somep[lace I simply cannot find it. It is not with the NAT controls where it used to be. How can I forward the ports as you indicate? Or can you piont my towards instructions to do so?

 

Thanks for all your help.

Re:Dual Wan Router (TP-Link ER707-M2) with Netgear RS700 as Primary
Thursday

My apologies for asking for help before I spent a little more time trying to work it for myself. I have spent some more time now...and failed. I did set port forwarding in the ER707 for the important IP addresses  in the RS700. I basically just duplicated the values from the Netgear router into the TPLink Virtual Servers page. I also tried to change the subnet mask from 255.255.255.0 to 255.255.255.240 (chosen at random from a table of valid subnet I found), but I could not get it to stick and gave up in the end. After that, I still found resources (a media server running on a NAS with a static IP with a wired connection to the RS700) on the network unavailable from outside.

 

No doubt I have made any number of laughable mistakes. Any advice would be appreciated.

1. What subnet (LAN addresses) are propagated by your Netgear?

2. What subnet (LAN addresses) are propagated by TP-Link?

  @RaRu The LAN address for the TPLink are  192.168.0.100  and  192.168.0.101. THe LAMN addresses in the Netgear are  192.168.1.2 through  192.168.1.56. The subnet masks are identical 255.255.255.0.

OK. Slow as I am I might have figured out where I went wrong. I should have forwarded all the important Netgear port of the the TPLink to 198.168.0.101, which is the TPLink LAN address of the RS700. Am I on the right track?

Well, it appears that my last attempt failed as well. Resources on the Netgear router are still inaccessible from outside. Here is my current (unsuccessful) port forwarding configuration. 192.168.0.102 is the internal TPLink LAN address for the RS700.
